RADIATOR.

Application tiled December 20, 1913.

Ylie it lmown that 1. JI'LIAN P. LYON, a eitixen oti the l'nited Statesof America, residing at Detroit. in the eounty of Wayne and State ofMiehigan. hare invented certain new and useful improvements inRadiators. ot whith the 'following is a specitieation, retlrenee beinerhad therein to the accompanying drawings.

My invention relates to radiators and more inlrtieularly to radiatorsemployed in eonnertion with explosion engines.

The invention has amongv the objeets thereof to provide an elieient anddurable strueture; to provide sueh a structure that may be easil) andeheaply manufactured; to provide a eonstruetion in whieh the cooling;etlirieney is materiali)l inereased over radiators now in general use:to eliminate to a material extent the coating ot' solder on thesurt'aees exposed to the air eireulating*r through the radiator: toprovide a strneture in whieh the water tubes are free, from solderedjoints: intermediate the sidesl ot' the radiator: and further to providea diamine. lsimple and ellieient water tube.

(ither olyieets of the intention will more fully hereinafter appear.

"he invention resides in the peeuliar ('onstruetion. arimrgements andeombinations ot parts, as will more fully hereinafter appear and aspxutivularly pointed out in the rlaims.

l'n the draw'ingsM-lfigure l is a pei-speet'ive view ot' a portion of aradiator embodying the intention: Vig. 2 is a fragmentary vin-tieniseetion ol. the strut-ture shown in Fig, E 1 Vig. I is a plan view ot'one of the,

t' are a plurality ot spared water tubes havungY their top and bottomedges eonnerted respeetirely to the members A\ and B. as will morei'uily hereinafter appear. "the tubes t are eul'h formed from a piero otliat metal l'olded upon itself to form a fiat tube. the bend ll #losingone edge of the tube while the free ends E F are preferably return bentand preseed together to close the Specieation of Letters Patent.

opposite edge. One end of each tube is inserted through a slot G in themember A and the opposite end of the tube is similarly engaged with themember B. The ends of -the tubes are suitably Connected to the headerspreferably by bending out the marginal edges H I that project throughthe header plates. and then closing the joint; between the plates andthe tube by solder.

Arranged between the tubes are a series of spaced tins J. each of whiehis composed ot a plurality of strips l( that tit between adjaeent tubes.,Preferably the tubes C are ot' a length to extend from the top headerto the bottom header` and ot a width to eX- tend from front to haelt ot'thel radiator. I (ind it desirable to form the tins J eaeh ot a singlepiet-e ot' metal preferably of a width to extend from front to bark ofthe radiator and ot' a length to extend eompletely from end to end otthe radiator, The metal iS slit to form the strips K and preferably themembers l( at their front ends are integral with a eonneeting seetion Lwhieh is interlorked with the t'ront edges of the tubes as by providingrslots al in the front edges of the tubes whieh receive the eonneetin;rportions. the eorresponding slots in adjaeent tubes being in horizontalalinement. In order to strenuthen the portion L the latter is preferablybent downward and then return bent so as to form the section L ofseveral plies ot metal. This arrangement not only adds strength to thefin but also, since the forward edge of the tube is composed of severalplies of metal. f "i ves the radiator the anpearanee of ay eomparativelyheavy structure. I `urthermore the eomparatively heavy interenqagingportions ot' the tube and the fin will permit the fin of the radiator tostand a eonsiderable thrust, w ithout damaging' the parts.

The sides of the strips l( are in Contact; with the sides of the tubes.and in order to inerease th(` etlieieney of the heat-Conducting jointbetween the tubesand the sections K, the edges of the latter are turnedat substantially risrht angles. formingr Hanges N of materially greaterwidth than the thickness ot' the metal. and the outer faees t) of Whiehbear against the tubes. The flanges N serve the additional t'unetion ofreinforeing and strengthening' tht` seetions K. thereby permittiu;r thetins to be formed of eomparatively thin metal. inet-easing the eoolingetiiciency of the fin. Preferably the end P of the sertionsy KY alsoturned so as to add additional strength to the .strips K.

llaeh oi the .sides (Q ll ot the tubes are preferably provided with aseries of cells H pressed outward therefrom and which are arranged inhorizontal rows 'l` extending. iu the structure illustrated. trom frontto bael; ot' the radiator. the cells of the rows in one side being outof registration with the wells ot the corresponding rows ot the oppwiteside. as: shown in Figs. El and 4. the eorrespoiuhng rows upon oppositiesides. however. are in ahnement. These row`1 "l` are spaced`sullieiently to torni channelf` l` between adjaeent rows. of a width tonicely reeeire the ttanges ot the strips K, thereby retaining the latteragainst vertical movement.

l find it desirable to so bend the flanges N that when the si rips K areengaged with the tubes. the flanges will tend to spread. which willn'iaintain a tight joint between the tubes and the flanges, rthis notonly will insure the tubes and the sections K being in heat-condite(ingeontaet at all times. but will also avoid play between these parts, andas the metal ot the tubes and the tins expands when the radiator becomesheated. in use the joints between the tins and the tubes are tightened.Furthermore the connection between the tubes and the tins beforedescribed permits a proper joint to be maintained between these memberswithout the use ot solder, materially increasing the heatemiduetirity otthe joint overa soldered one, as will be readily appreciated.

For certain uses I find it desirable to provide the strips K withopenings 'l` so as to allow a circulation ot' airvertieally ot' theradiator. as well as laterally. In forming these openings in the stripspreferably the metal is merely ruptured so that the area ot the surt'aeeot the strip which is exposed to the air circulating through theradiator is not redueed. Similarly it will be noted that all the metalof the blank from which the tin .T is formed is used. since the turningof the flanges N provides the necessary width to the slots for receivingthe tube..

The sides ot the tubes may be spaced in any suitable manner, but spacingis ede@ tively :momplished by forming one or moron-pret'erably apluralityf-ot' inwardlyextending projections U on the tube sides. aswill be best seen upon reference t,o l `igs. S and 4.

ln assembling the radiator the tubes are engaged with the header platesand the edges H I spread. The tins are then engaged with the, tubes.which may be easily and readily accomplished since the channels U formguides which properly position the -strips ot the. tins. Preferably insealing the joints and eonneeting they parts together, the top andbottoni of the radiator are merely dipped sutliciently to seal the jointbetween the plates and the edgesI ll I, the front side merely sutlieientto .seal the joints ot the tubes closed by the edges E F and solder theconnecting portions L to the tubes, and the back side dipped to attachthe tree ends ot the strips K to the tubes. This manner ot dipping notonly saves solder, thereby reducing the cost of manufacture and also theweight ot the radiator, but increases the cooling elliciency. sinceneither the tins nor the tubes are coated with solder. The connectingtogether of the parts and the sealing ot' the joints, however, may beeffected in any suitable Way and it might be found desirable, forcertain uses, to dip the entire radiator after the partshave beenassembled.

From the foregoing rflescription it will be readily apparent that theradiator is one that may be easily and cheaply manufactured and readilyassembled. and that an exceedingly durable structure is provided; alsothat there are no joints in the tubes interlnediate the sides of theradiator but that they seam of the tube positioned so as to be readilyaccessible in ease the seam leaks.

wWhile l have shown and described the preferred torni of my invention, Ido not desire to limit my protection to the particular constructionillustrated, but consider the invention to be ot sutlieiently broadscope to cmbody various modifications. v
